The series offers single, dual, and triple channel versions in either voltage feedback (OPA690), current-feedback (OPA691), or fixed-gain video buffer (OPA692) topologies.
The OPA690 is a unity-gain stable amplifier with optional disable that can deliver a 1V to 4V output swing with >150mA drive current and 150MHz bandwidth, from a 5V supply. This makes it suitable for use as an RGB line driver or single supply ADC input driver.
The dual OPA2690 supports high slew rate differential I/O requirements, while the triple OPA3690 enables higher order active filters in a single package.
The OPA691 operates from a 5.1mA supply current and offers a slew rate of 2.1kV/?s and output power of 190mA, making it suitable for multi-line broadcast video interface applications. The dual OPA2691 addresses the differential I/O requirements of xDSL, while the triple OPA3691 is suits RGB line driving where gain or frequency response shaping is desired.
The OPA692 broadband, fixed-gain video buffer amplifier has an optional disable feature and delivers a 1V to 4V swing with >120mA drive current and >200MHz bandwidth, from a 5V supply.
Suggested resale pricing in 1,000 piece quantities starts for the single channel versions at $1.50 (OPA690), $1.45 (OPA691), and $1.35 (OPA692). |
